ARVEY-'WARE CORPORATION, -A CORPORATION OF DELAWARE i i I DEVICE FOR. SEALING CONTAINERS applicati@ mea January as, 192s. seriarm. 249,312.

The present invention relates to a device for applying covers, and seals therefor, to containers, and refers more particularly to an apparatus especially designed for quickly and easily applying and securely locking and sealing covers upon containers.

The cover which the deviceof the lpresent invention is adapted to apply and securely lock to the container has cooperatively associated with it a metal band of-substantial width adapted to encircle the wallof the container adjacent the rim thereof. Said band is provided with flanges'extending inwardly at anangle from its upper and lower edges, the upper flange being adapted to contact the upper surface of the cover While the lower fiange is adapted to engage the container wall. The cover and band, before application to the container, are brought together in engagement as a unitary structure and are applied as a unit.

Briefly, the device ofthe present invention comprises a series of shoes adapted to surround the metal band and compress the same firmly against the container wall to diminish its diameter and cause itl to tightly grip the wall of the container and embed the lower in-' wardly extending fiange of the band in said wall. The device is eiicient in use, permitting the cover to be rapidly attached and sealed in place. By the device of this invention, there is applied a permanent seal, stronger and more theft-proof than formerV seals.

Other features, advantages and objects of the invention will be more particularly apparent from the following detailed description. l

In the drawings, I

Fig'. 1 is a fragmentary side elevational view illustrating a container with the sealing device, shown in section, in inoperative or y open position, preparatory to the step of apthe device in open position, preparatory toapplying the cover, and' seal therefor, to the container;

' Fig. 5 is a fragmentary sectional view of the device in inoperative position in the act of sealing the container; and

' Fig.- 6 is a fragmentary sectional view of the container showing the cover sealed to the container subsequent to the use of the device of the present invention.

Referring more in detail to the drawings, 1 designates a metal frame of ap roximately thf-e same peripheral size and s ape as the top edges of the container onjwhich it is used. An upstanding pin 2 may be suitably attached to the .frame 1 having vslidably mounted thereon a collar 3 having grooves 4 adapted to engage the ends5 kof levers 6. The collar 3 may be moved upwardly and downwardly on the pin 2 by means of levers ,7 which may be pivoted at 8 on fulcrums 9 and also be pivotally attached at 11 to ears 12 of the collar 3. The fulcrums 9 may be pivotally attached to the frame 1 at 10. Thus as the levers 7 are moved downwardly, the collar 3 is moved upwardly, carrying with it the ends 5 of the or otherwise fastened to separate shoes 15,-

preferably having curved inner faces 16 adapted to conformwith the contour of the side wall of the container tobe sealed. The inner faces 16 of the shoes 15 may be beveled as shown in the drawings tocause the shoes to conform at all points in cross section with the sloping wall of the container. It is obvious, of course, that the inner faces of the shoes may be fiat and longitudinally straight where the device is to be used for applying a cover, and seal therefor, to a container having straight sides.

A suitable container 17 of substantial 'depth may be provided, which may, for instance, comprise felted or moulded fibre, wood, metal or the like. A cover 18 may be provided which may be of wood or any other material shaped to conform to the upper rim of the container. For the purpose of securely locking this cover 18 in position on the conwith it which has a body portion of substantial width and which is adapted to surround the wall adjacent the rim of the container.` From the upper and lower edge, respectively, of the body portion of band 19 may inwardly project an upper flange 20 and a lower liange 21. The upper flange 20 is adapted to contact the upper surface of the cover 18 while the peripheral edge of the mounted on the frame, a shoe mounted on one I flange 21 is adapted to Contact the wall-of the container, preferably in such a manner that it bites into this wall to a limited extent. The band 19 -may be split at one or more points, as illustrated at 22, to aid in its application to the cover 18, suitable means 23 being provided to secure the ends together. In the operation of the device, the cover and band are irst brought together and united into a unitary structure. This unitary structure, comprising cover and band, is then applied to the container and the device of the present invention placed thereon, the frame 1 resting upon the cover 18 and the shoes 15 hanging'loosely in a position adjacent the metal band, the relative positions ,of the elements referred to being illustrated in Figs. 1 and 4. As the levers 7 are moved downwardly under the force applied, for instance by manual pressure, the collar 3 is moved upwardly, carrying with it the ends 5 of levers 6, which causes the shoes to move f inwardly to bear against the band 19 until the device assumes the position illustrated in Figs. 2 and 5 and the band has been decreased iny diameter suficiently to cause the lower Vflange 21 to bite into the wall of the container. The upward movement of the collar 3. may be regulated by the movable thumb screw 23 which may be threaded to pin 2. Sufficient pressure is applied against L the band 19 by the shoes 15 to cause the former to diminish in diametery andk tightly grip the container wall, causing the liange 21 `to be embedded therein to more securely lock ,45 the cover 18 to the container. I y

It is to -be understood that the use 'of the de vice of the present invention is not to be limited to the specific types of containers and covers herein described; for instance, the cover may be made `entirely of metal and the cover and band may comprise one piece.

I claim as my invention: t 1. In a. closing device, a frame including a vertical stem, a slidable collar upon said stem, a plurality of levers cooperatively associated with the collar and divergin radially therefrom, a shoe mounted on t e outer end of leach lever, the shoes forming substantially an annular ring about the stem as Q0 an axis, means for'simultaneously moving `the shoes, and anv adjustable stop positioned upon `saidstem` for limiting movement Aof the collar.' 2. VA closing device, including in combination, a frame, a.p1ura1it`y of levers pivotally In testimony whereof I aix my signature.
